SPECIFICATION forming part ef Lettere Patent No. 654,287, dated. July 24, 190e.

Application filed .Tune 9, 1896. Serial No. 594,854. (No model.)

To 'ctZZ whom t may concern.-

Be it known that I, ROBERT SEEGER, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a speciiication.

My invention relates to hydrocarbon-burners designed for illuminating purposes; and the object which I have in view is to provide a hydrocarbon-burner particularly adapted for use with street-lamps; and the invention of this application is an improvement upon the invention shown and described in my former application for patent upon y vaporburners, tiled November 10, 1894, Serial No. 528,414 5 and the especial objects of the present invention are to provide means for vaporizing the oil in a suitable retort Within the body of the burner and leading the vapor to the removable plug and the mixing-chamber, also to provide improved means for heating the part of the burner within which the oil is vaporized, and also to provide an improved construction which permits the burner to be readily cleaned. y

To the above-named ends this invention consists in the constructions and combinations hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved burner. Fig. 2 is a similar view with the shield and the tapered plug removed. Fig. 3 is a plan view. Fig. 4 is a transverse vertical section.- Fig. 5 is a horizontal section on the line c oo of Fig. 1.

In the drawings, 2 represents the vertical tube, the upper part of which is provided with the tip 3, having a slit 4, and the lower part of which constitutes av mixing-chamber and is provided with the series of horizontal slots 9. The lower end of the tube 2 receives the plug 8. The lower part of the burner is preferably provided withthe ear 22 and the plug with the lug 23, having an inclined lower face, by means of which the plug may be locked in position in the burner. The plug is also preferably provided with the handle 24, by means of which it may be grasped and turned for the purpose of insertion or removal. These parts are all substantially the same as the corresponding parts of the burner shown and described in my former application for patent hereinbefore referred to. The lower end of the plug 8 is preferably provided with the plug 25, which is driven into the lower end of the hollow plug 8 for closing the same. Ascrew or other means might of course be used if preferred for closing the lower end of this plug. The hollow plug 8 is provided with a small opening 10 in its top through which tthe vapor'passes to the mixing-chamber. The oil is supplied to the burner through a tube or pipe 11, which enters a suitable nipple 12. Thel tube 11 is preferably provided with a packing of cotton or other suitable material, which forms a strainer for preventing any sediment or similar material from passing into the burner. opens into a small chamber 14, above which is the hollow dome 15. This dome screws into the top of the chamber 14, and the chamber and dome together form a retort in which the oil passing into the chamber through the pipe 11 is vaporized. A tube 16 has its open end near the top of this retort, its lower end being secured at the bottom of the chamber 14. A duct 17 forms a continuation of the opening of the tube 16 and extends downward, preferably, on an incline to a point near the wall of the tube 2, where it communicates with the horizontal duct 18, which in turn communicates with the tube 2. The hollow plug 8 is provided with an opening 19, which when the plug is in place comes opposite the duct 18, thus permitting the passage of vapor from the retort through the tube 16, the ducts 17 and 18, and into the plug 8. I prefer to form ay small opening 21k inthe Wall of the tube 2 opposite theduct 18, so thatwhen the plug 8 is removed the duct 18 maybe cleaned out by means of a wirein'serted'through the opening 21. As the duct 17 forms a continuation of the opening in the tube 16, both be-- ing in a straight line, by removing the dome 15 a wire :may be inserted through the tube 16 and duct 17 and the same be thereby cleaned out, and any residuum thatcollects The nipple 12 therein may be forced downward and into andthrough the duct 18, the plug 8 being removed,

and out through the open "lower end of theV chamber and the space above the shelf 26.4

The ends of this shield do not extend close to the walls of the tube `2, so that air is permitted to enter between said tube and the ends of said shield. A portion of the gas from the tube 2 escapes through the openings 28, and being ignited a flame is continuously maintained within the shield 29 around the retort-chamber. The upper part of the dome 15 is also in close proximity to the top of the burner, so as to receive a large amount of heat therefrom.

The operation is as follows: The heavy oil employed enters the retort-chamber and is vaporized therein. The vapor passes down through the tube 16 and the ducts 17 and 18 and into the hollow plug 8, from which it escapes through the opening 10. It is mixed with the air which enters the tube 2 through the slots 9 and passes to the burner 3. By removing ,the plug 8 said plug may be readily cleaned of any residuum that collects in the openings 10 and `19, and by removing the dome 15 the tube 16 and the ducts 17 and 18 may be readily cleaned out.

It will be understood that the tube 16 and ducts 17 and 18 will only occasionally1 require cleaning. I find it an advantage, however, to remove the plug 8 each day and clean out the small opening 10. In this instance, as in 1n former patent, the plugs 8 are preferably al made interchangeable. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent--A 1.
